as someone who loved md i do understand where you are coming from but i now use priori and love it! i must admit it did take alot to persuade me but i went on training before i took on the brand it was £100 which was then credited onto my account when i took on the brand. for 3 days intense ADVANCED skin care £100 isnt bad if you then decide you dont like it! i only have coffeeberry and aha in my salon, basicaly they have combined all of the md products into 1 of each, only 1 cleanser, 2 correcters 1 for oily (gel also used as a "spot on treatment" 1 for everyone (cream) 1 moisturser which because it is water based in sutiable for all skin types! even acne! as an oily skin still need to be hydrated, and 1 spf which doesnt need to be patted on and applys like a moistser.
it contains lactic and glycolc but the main ting in it is lactic beause it is actually smaller that gycolic (which md dont tell you) the peel is only on for 3 min and doesnt ever increase as it is so strong, it is stronger than the alpha peel in md.
lol sorry i am preaching as a converted. i was given tragets by md to do 3-4 facials a DAY!!! which as a brand new, no client buisness was completly unachivable! also they said i had to buy £7000 to get recognition on the website within a year. they didnt like the fact that i only have 1 room and i found the lady i delt with who was covering materinity in not simple terms a bitch!!! as someone who knew the prodcuts inside out and going from a salon where i was sellin over £600 of the stuff a month they should have had a tiny bit more respect!!
rant over

xx hope that helps!!
